This IEEE conference talk explores the perception of visual variables on wall-sized tiled displays in immersive environments through two user studies. Learn how researchers from Utah State University and Université Paris-Saclay investigated elementary visualization reading tasks in VR, comparing three different virtual display arrangements and analyzing how they compare to real-world settings. Discover the surprising finding that virtual curved walls resulted in smaller errors than real-world flat wall displays, despite requiring longer task completion times. The presentation also examines the impact of four 3D user interaction techniques on performing elementary tasks on virtual wall displays, providing valuable insights for designers of immersive visualization environments. The 13-minute talk includes findings, limitations, and directions for future research in this emerging field of immersive analytics and visualization.
